从阴阳四时之理探讨“七损八益”内涵

Discussion of the Connotation of “Sevenfold Reduction and Eightfold Boost” Based on the Principle of Yin-Yang and Four Seasons

"七损八益"是由《素问》提出的保身长全之道,历来医家众说纷纭。唐代王冰释其为房中术,且将其与男女天癸之数相联系,且随着近年出土的《天下至道谈》论述"七损八益"为房中术,此观点影响甚广。遵从《素问》原文,从阴阳角度,借助阴阳八卦之理对此进行探讨,认为《素问》中的"七损八益"为调用阴阳之大道,可用于指导房中术的养生。无论"七损八益"或是男女天癸之数皆源于阴阳四时之理,养生之大法在于顺四时阴阳之变,进一步强调阴阳四时变化与人体生长衰老之间的联系。

The principle of'sevenfold reduction and eightfold boost'proposed in Basic Question for the health and longevity.However,this principle was explained differently by scholars in history.WANG Bing in the Tang Dynasty explained that it belonged to coition medicine and was related to the number of Tiangui number of the male and female.Besides,in the A Discussion on Universal Law found through archeological excavation recently,'sevenfold reduction and eightfold boost'is explained as coition medicine.Therefore,'sevenfold reduction and eightfold boost'is widely accepted.According to the original sentence in Basic Questions,based on the yin-yang theory and eight trigrams,it is proposed that this principle is the major principle for applying yin-yang,and it could be applied to guide the health cultivation in the coition medicine.Both'sevenfold reduction and eightfold boost'and Tiangui number stem from yin-yang and four seasons,and the major principle for health cultivation is to follow the variation of four seasons and yin-yang.Therefore the variation of yin-yang and four seasons is closely related to the growth,development and aging of the human body.
